Abstract

Process for separating chlorinated polyvinyl chloride from its solution, in tetrachloroethane, characterized in that it comprises introducing said solution into a stirred mixture of one part of tetrachloroethane and from 0.25 to 0.6 part of methanol, by volume, and at the same time time, add methanol alone or mixed with tetrachloroethane to the indicated mixture, to maintain the volumetric ratio of tetrachloroethane to methanol in the mixture, within the same limits.
